(No model.)

To all whom it mag/concern:

Be it known that I, KING CAMP GIILETTE, a citizen of the United States,and a resident of London, England, have invented new'and use--v -spectto which itis positioned bymeans 'of pins or the like passingthrough'the perforations in the blade, such a razor being described andclaimed in my application for United States LettersPatent, Serial No.84,552, filed December 3, 1901, of which application this presentapplication is a division.

The razor specifically shown and described in my said prior applicationhas a thin ilexible blade provided with two opposite cutting edges, andthe two sides of the4 holder are made alike, the handle beingsymmetrically disposed midwaybetween them, so that either edge of theblade can be used without altering its position in the holderzand mypresent improvements are hereinshown and described as embodied in a'razor hav'igv the same general characteristics-that is to say; adoubleedged .flexible blade, a double guard, and asymmetrically-disposed handle; but it is to be iinderstood that thisparticular construction and arrangement of these parts isnot essentialto the main features of my present invention.

Figure 1 is an end elevation, partly in section, of the complete razor,showing the parts in position ready for use. Fig. 2 is a centrallongitudinal section through the same. Fig. 3 is a view similar to Fig.l, but .showing the parts of the razor partly separated. Fig. 4 is aplan view of the outer face of the head of the razor, and Fig. 5 is aplan view of the razor-blade.

Referring to the drawings, 2 indicates the blade of the razor, which isusually made of sheet -steel having a uniform thickness of about sixone-thousandths of an inch and'provided with two opposite cutting edges3. The

holder comprises a backing 4, a guard-piece 5. a handle 6, carried bythe guard, and means for moving the guard and backing toward or fromeach other. backing 4 is of the same length as but slightly narrowerthan the blade 2, being thus adapted to support the blade near itscutting edges and impart the necessary rigidity thereto when-the bladeis secured in place. The longitudinal edges of the guard 5 are of thesame gether 1 provide a pin or bolt 9, carried by the backing and havingits free end threaded to engage the internally-threaded hollow end ofthe handle 6, whichV is preferably located vwithin a sleeve or socketl0, secured to or formed integral with the guard. and is held to turn'in said -sleeve by means of a pin 11, passing through the wall of thesleeve and entering an annular groove 12, cut in the handle.

When the parts are assembled, the blade 2 is located between the guardand the backing, and in order to position the blade the backing isprovided with pins or lugs 13, adapted to pass snugly through openingsor perforations 14, formed at the proper points in the blade. The guardis preferably positioned by means of the same pins, which are made longenough to pass through perforations 15, formed in the guard, andregistering with the perforations 14 in the blade when' the parts are inproper relation. l

When the blade and guard are double-edged, as shown, the sleeve 10 islocated at the center of the guard and extends at right angles thereto,and the blade is centrally perforated, as at 16, to receive the bolt 9;the pins 13 and the registering perforations 14 and 15 in the blade andguard being also located midway In the present instance the between theedges of the holder and at equal dmetrical arrangement of the handlepermits either edge of the razor to be used with equal facility. V

In the construction illustrated the adjacent surfaces of the guard andbacking conform in area and contour, or substantially so, thus providingrigid supporting-surfaces for the blade throughout practically theentire area I ofthe latter when clamped between said parts,

and in order to utilize the tlexibility andelasticity of the thin bladefor the purpose of obtaining an adjustment of its cutting edges towardand from the edges of the guard these conforming-surfaces ofthe guardand backing are somewhat curved transversely, so that the blade is benttransversely and its cutting edges are caused to approach closer andcloser to` the notched edges of the guard as the guard and backing aredrawn together or permitted to' spring away from said notched edges asthe guard and backing are separated. In Fig. 4 the backing 4 is shown asprovided at each corner with a lateral projection 17, adapted to extendslightly beyond the edge of the corresponding corner of the blade andlie close against the same, thus covering the rear side thereof. Thisfeature, as well as an arrangement similar to that above described forad.-- justing the cutting edges of the blade, is described and claimedin my prior application,

Y Serial No. 84,552, above referred to, and isincluded herein inorder'to illustratethe pref It is one of the -features of my present im'provements that after the guard and handle have been detached from thebacking the blade may. still be held in place on the'back- `ing by'means of the positioning-pins and may b'e grasped by its endsandreadily applied or removed without having to be slid laterally.

as has been the practice heretofore. I claim as myinvention- 1.` In arazor, the combination with forated blade, of a holder comprisinga han#between` the sides of a supporting-framework,

die, a backing provided with positioning-pins l a per# arranged to passthrough the perforations in the blade, a guard, and means for clampingsaid blade between the backing and the guard.

2, In a razor, the combination with a perforated flexible blade, of aholder comprising a handle, a rigid backing .forming a support for saidblade and provided with positioningpins arranged to pass through theperforations therein, a guard, and means for clamping said blade betweenthe backing and the guard.

3i In a razor, the combination with a pertral screw-threaded bolt, aguard curved transversely to correspond with said backing and aving itsopposite longitudinal edges notched, a flexible blade having twoopposite .cutting edges and provided with perforations arrangedto'receive the bolt and positioningpins, and a handle having its innerend internally screw-threaded to receive said bolt.

5. Ina razor, the combination with a perforated blade of a holdercomprisingaguard, a handle, a backing, and clamping means passingthrough the blade, said blade and backing being so formed that the endsof the former project beyond the ends 0T the latter.

6.' In "a razor, the combination with a perforated blade .having twoopposite cutting edges, of a holder comprising adouble guard havingperforations corresponding to those in the `blade, a backing providedwith posi- IOO tioning-pins passingthrough the blade and guard, ahandle, and means for detachably clamping the blade between said backingand guard.

7. In a razor-,Va holder comprising a backing provided withpositioning-pins and with a central screwthreaded bolt, a double guardprovided with"perforatious adapted to receive said positioning-pins andbolt, and a handle provided with an internally-screw-threaded nutadapted to receive said bolt.

8u. In'a razor, a holder comprising a trans- `versely-curved, rigidbacking provided with positioning-.pins and with a screw-threaded bolt,a -guard curved transversely to correspond with said backing andperforated to re ceive said positioning-pins and-bolt, and a handleprovided with an internally--screwthreaded nut adapted to receive saidbolt.

9. A safety-razoromprising a back plate,

IIO

a clamping-plate, a. handle piojecting from 'means for securing theplate, bladeaud guard said plates at substantially a right angle, atogether. v

sleeve connected to said clamping-plate and mounted on the handle, andmea-ns for adjusting said plates toward and from each other.

l 10. A safety-razor comprising a back plate having lugs, a blade, aguard, both the blade and guard having openings for said lugs, and

1n testimony whereof I have hereunto subscribed my name this 10th day ofMay, 1904.
